Variations

Coditos are not available in the UK, as far I can ascertain, although it may be found as elbow macaroni. They are similar in shape to the Italianpipe pasta and this type can be used instead.
Elicoidali is another fairly close equivalent that can be purchased directly from Waitrose.

I already had some homemade garlic mayonnaise, but had no idea how much would be made from 500 ml of olive oil, however, 3 good tablespoons of mayonnaise seemed just fine. I also garnished the salad with a little smoked paprika to add a bit of extra interest.
Many people like to use Cream in this salad because it reduces acidity in the dish due to the mayonnaise.
